Abstract

PCT No. PCT/EP94/02405 Sec. 371 Date Aug. 21, 1995 Sec. 102(e) Date Aug. 21, 1995 PCT Filed Jul. 21, 1994 PCT Pub. No. WO95/04910 PCT Pub. Date Feb. 16, 1995In a charging material preheater for a metallurgical smelting plant having a shaft (5) which has closure members (7, 8) which are pivotable by a control member (6) and which include fingers (9, 10) which are arranged parallel and at a spacing relative to each other, the fingers (9, 10) of a closure member (7, 8) are mounted with a central portion in a first rotary mounting (12, 13) and in a second rotary mounting (21, 22) of the frame structure (2) with an outer portion which is passed outwardly through an opening (14, 15) in the shaft wall, by way of an elbow lever mechanism (16, 17), and lever arms (18, 19) of at least two elbow lever mechanisms are connected together by a connecting member (23) which is pivotably engaged by a control member (6) which is supported in a third rotary mounting (26, 27) of the frame structure (2).
